Abstract: A high-speed induction motor with a rated power of 2 kW and a rated speed of 59 000 r/min was designed. According to the high loss brought by the motor at high speed, the iron-based nanocrystalline alloy with better performance was selected as the stator core material of the high-speed induction motor. In the case of high harmonic torque generated by the induction motor at high rotation speed, the motor was provided with a high starting resistance by adopting a closed circular groove rotor with an end ring, so that excellent starting and running characteristics were obtained. The rotor structure of the induction motor was subjected to stress analysis by using the ANSYS software, and the reliability at high rotation speed was verified. In the end, the finite element model of the high-speed induction motor was established, and the performance comparison was carried out by the silicon steel DW310 _ 35 motor with the same structural parameters. The results showed that, compared with that of the silicon steel DW310 _ 35 motor with the iron-based nanocrystalline alloy 1K107 stator core, the total loss was reduced by 81.2 W, the efficiency was improved by 4.5%, and the power factor was increased by 0.031.
